Electric Isolation

Greetings from team 5145!

As our team nears completion of our robot, we are currently reviewing the inspection checklist. Rule 37 states that the electrical system must be isolated from the frame, however, we have discovered that the robot frame is at the same potential as the ground on our battery. After further inspection, we discovered the source of this to be the screws holding the PD to the frame of the robot. Is this okay, or do we need to mount the PD on a non-metallic mounting surface, or use nylon screws? From a safety standpoint, we are not overly concerned, as the open circuit resistance between the positive power terminal and the frame is a couple hundred kohms. We just want to make sure we are in compliance with the rules.
